You get what you pay for, cheaper sticks are just that and won't last if you are a heavey hitter. Marching sticks although large in size ,are made of softer woods and won't last very long, as well as be hard to play with.
The Vic Firth Rock Hickory should be o.k but get the plastic tip model instead if you are breaking tips, or try a harder wood type like oak. If you can handle big sticks try the Mike Manginin laminated model. If you are hitting so hard to break sticks there is usually a reason. Do you need to mike up the drums for more volume ? Do a a self review of your playing technique, where are you hitting the drums and cymbals, and are you using arm movements and not allowing the stick to bounce, rigidity creates shock and wear out sticks quicker.
Straight on blows to cymbals will do it too, and possibly damage the cymbals as well.
Try glancing blows. If you continually use rim shots, let's face it, the metal hoop is going to win in the end over the wood stick.
Plastic tip sticks are likely to dent heads only if the drums are on too much of an angle and tensions too loose.
Handy hint
When i was playing rock and using many rim shots i would often get a double life out of the sticks. When the tips fell off a drum stick, it was these sticks i saved and used the butt end to play the snare hand with as it was generally the middle of the stick that wore out, so the tip not needed.
